1、Designation:D604602(Reapproved 2012)Standard Classification ofHydraulic Fluids for Environmental Impact1This standard is issued under the fixed designation D6046;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revisi
2、on.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This classification covers all unused fully formulatedhydraulic fluids in their original form.1.2 This classification establishes cate
3、gories for the impactof hydraulic fluids on different environmental compartments asshown in Table 1.Fluids are assigned designations within thesecategories;for example PwL,Pwe,and so forth,based onperformance in specified tests.1.3 In the current version of this classification the aspects ofenvironm
4、ental impact included are environmental persistenceof which biodegradability is one component and acute ecotox-icity.Although environmental persistence is discussed first,thisclassification does not imply that considerations of environ-mental persistence should take precedence over concerns forecoto
5、xicity.1.4 Another important aspect of environmental impact isbioaccumulation.This aspect is not addressed in the presentclassification because adequate test methods do not yet exist tomeasure bioaccumulation of hydraulic fluids.1.5 The present classification addresses the fresh water andsoil enviro
6、nmental compartments.At this time marine andanaerobic environmental compartments are not included,al-though they are pertinent for many uses of hydraulic fluids.Hydraulic fluids are expected to have no significant impact onthe atmosphere;therefore that compartment is not addressed.1.6 This classific
7、ation addresses releases to the environmentwhich are incidental to the use of a hydraulic fluid.Theclassification is not intended to address environmental impactin situations of major,accidental release.Nothing in thisclassification should be taken to relieve the user of theresponsibility to properl
8、y use and dispose of hydraulic fluids.1.7 This classification does not cover any performanceproperties of a hydraulic fluid which relate to its performancein a hydraulic system.1.8 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibil
9、ity of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2D5291 Test Methods for Instrumental Determination ofCarbon,Hydrogen,and Nitrogen in Petroleum Produ
